1.What is the equivalent settings for option strict on and option explicit on in c# ? 2.I have a class in another project ( VC++). I want to access the methods and properties in VC++ class from my project in C#. The VC++ is a standalone EXE project and hence I cant add any reference to my project. But in VB I found a method named GetObject( "AssemblyName") to retrieve the object in runtime. As VB.Net supports early binding by setting option explicit ON , the methods and properties of the VC++ class can be accessed by creating an instance of system.object. Can anyone please tell me how can we do the same in C#.net ? 3.Is there any C# equivalent function for "ON ERROR RESUME NEXT" in VB ? We can use Try catch but catch block will be excuted if any error occur in try block.

Thanks Dave for your reply. I tried the following 1)<STAThread()> _ and <MTAThread()> _ before the class is intialized. Is it the correct place ? 2)System.Threading.Thread.CurrentThread.ApartmentState = Threading.ApartmentState.STA But still no luck. I verified after changing threading model in Registry. It is getting reflected and the Guid is matching with my code. Any more suggestion please.

Hi All, I upgraded a project from VB to VB.net ( ActivexDll). After converting while debugging I am getting an error "E_nointerface". Can any one please tell me why do we get this error? Through goggling I found some results telling it may be due to threading conflicts. If so please tell me how to set threading in VB.Net.( In VB I found that threading mode is set to "Apartment" in project properties similarly how do we do it in Visual studio 2003 )
